SOLE-LAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 627,035, dated June 13,1899.

Application filed September 14, 1898. Serial No. 690,935. (No model.)

To all whom it may concern:

Be it known that LERASTUS E.WINKLEY, a

- such as will enable others skilled in the art to which it appertainsto make and use the same.

The present invention relates generally to improvements in sole-layingmachinesof a type embodying a shoe-supporting jack and pressing-form,and more particularly to an improved connection between the form and itsactuating-lever, whereby the pressure of the form on a shoe-sole isequally distributed over the surface of the sole and means are providedwhereby an excess of pressure is taken up and injury to the machineprevented.

The present invention is applied to the machine illustrated in my priorpatent, No. 557,744, of April 7, 1896, and is illustrated in theaccompanying drawings, in which Figure 1 is a side view of a portion ofsaid patented machine with portions of the formactuating lever brokenaway to illustrate more clearly the present invention. Fig. 2 is a topplan view of a portion of the formactuating lever and form; and Fig. 3is a section on line 3 3, Fig. 2, looking in the direction of the arrow.

Similar letters of reference indicate like parts in the several views.

It is of course understood that the accom:

.panying drawings illustrate such parts of the patented machine as arenecessary to indicate the connection of the present invention, and it isto be further understood that .the present invention is applicable toother forms of sole-laying machines, my said patented machine beingselected merely as a matter of convenient illustration.

In the drawings, A represents a portion of the spider-frame, whichsupports the jacks B (only one shown) and upon which are mounted theform-actuating levers 0, (one shown,) which support the sole-pressingforms D, (one shown,) all of which parts may be and conveniently are,except as hereinafter noted, substantially the same in construction andorganization as corresponding parts shown and described in said LettersPatent.

In the illustrated embodiment of my invention the form D comprises anelastic press ing portion 61, which is supported by a rigid form-carriercl, the toe portion of the elastic pressing-form, however, being mountedupon a fore-part rest (1 movable independently of the form-carrier d.The construction in this respect is substantially like that shown anddescribed in United States Letters Patent to George II. Gifford, No.584,038, of June 8, 1897.

In accordance with the present invention the forrn-carrier is supportedupon a tipping bed, which is mounted upon the form-actuating lever G,theconnections between the formcarrier and the tipping bed being of suchcharacter as to permit a movement of the form-carrier bodily toward andfrom the tipping bed, the arrangement being such that the form andform-carrier can tip longitudinally about the tipping center of the bedand at the same time move bodily toward and from said bed, andsuitably-placed springs are provided to control the bodily movement ofthe form-carrier toward and from its bed.

As shown in the drawings, II represents the tipping bed, which ismounted upon and free to tip about a fulcrum-pin h, supported atopposite ends in the side bars 0 c of the lever O. From the top of theform-carrier d are projected the bolts 7L which are extended throughbolt-holes h in the tipping bed H, through which they are free toreciprocate and by which they are guided. The bolts 72,2 are providedwith supporting-heads 71;, which overlap the tipping bed H and supportthe form-carrier d. From the top of the form carrier cl is alsoprojected a tubular sleeve (1 which receives the shank-block-adjustingspindle d, (substantially as shown in Letters Patent to Giffordhereinbefore referred to.) As shown in the drawings, the tubular sleeved is projected through a recess 72 in the tipping bed I I.- In thepresent embodiment of my invention I have provided two coiled springs71. and h on opposite sides of the fulcrum-pin h, which control thebodily movement of the form-carrier d toward and from the tipping bed H.One of said springs 72,

may be and conveniently is coiled about the guiding-bolt h and the otherspring 77, about the tubular sleeve 01 one end of each springof alateral movement along its fulcru m-pin h. It is to be understood thatboth the tipping and lateral movements of the bed H are movements ofadjustment, and means are provided whereby after the form has beenseated upon the sole of a shoe and the bed H been brought into theproper longitudinal inclination and lateral position to position theform upon the sole the bed H may be clamped to prevent further tippingor lateral movements and the machine thus adjusted to properly operateupon a series of similar shoes. The bodily movement of the form,however, as controlled by the springs h and h occurs during theoperation of the machine and prevents injury to the lever O or otherparts of the machine by undue pressure.

The clamping device of the machine of the drawings is represented at Land, as shown, consists of a plate'or bar Z, which rests upon and ismovable along a cross bar or brace Z, extended between the side bars 0 cof the form-actuating lever G. The bar Zis held in position by means ofa set-screw Z which extends through an elongated bolt-hole Z in theplate or bar Z into a threaded bearing in the cross bar or brace Z. Fromthe bar [are projected the ears Z X, which embrace one end of the bed H,extending along opposite sides thereof. Between the ears Z Z is extendeda clam ping-bolt Z which is provided at one end with a clamping-head Zand threaded at its opposite end to engage a threaded bearing in one ofthe ears Z By setting up the bolt Z the ears Z Z may be drawn togethersufficiently to pinch the bed H and prevent any tipping movementthereof. By setting up the set-screw Z the plate or bar Z is clamped tothe brace Z and any lateral movement of the bed H thereby prevented.

While I have herein described means for clamping the tipping bed toprevent its'tipping during the pressure movement of the machine, Idesire to state that the present invention is not limited to aconstruction wherein such clamping means are present, for it may bedesirable in some cases to allow the bed H to tip freely during thepressure movement of the machine,and I consider such a constructionclearly Within the scope of the present invention.

j The operation of my invention has been' sufficiently described inconnection with the foregoing description of its construction andorganization.

Itherefore claim as new and desire to protect by Letters Patent of theUnited States-- 1. In a sole-pressing machine, the combination with apressing-form and its actuating-lever, of a tipping bed carried by saidlever, yielding connections between the form and bed, and clamping meansto clamp the bed to prevent its tipping movement, substantially asdescribed.

2. In a sole-pressing machine, the combination with a pressing-form andits actuating-lever, of a laterally-movable tipping bed supporting theform, and clamping means to clamp the bed to prevent its tipping andlateral movements, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
